Take a look at this video. Its for HP Tuners but you should be able to do everything in the open source tools. Just follow the part about failing the MAF sensor and setting the proper DTC's. We usually run speed density on our jeeps...one less sensor to fail when you fill the intake full of water......

I have been experimenting with logging. Made a log on the way to work this morning. When I try the log playback function it loads up the parameters from the log but I get this error: Error, LoadLogFile line 2097: String was not recognized as a valid DateTime. Then if I hit the play button I get: Emp...

I suspect he is talking about histogram/tables in megalogviewer but I could be wrong. I have just started experimenting with megalogviewer and it looks pretty good. I just dont have any real logs from pcmlogger to feed it yet. If anyone has some sample logs from pcmlogger they want to send me feel f...

Just a quick add on....I had him try it with the allpro cable on the same system and it works.

Has anyone seen this happen? This was an attempted read from an 03 or 04 silverado on the bench from a friend of mine. The read seems to go fine...check the end of the log for the error messages. This same laptop/OBDX Pro VT can read and write the 0411's just fine. [06:08:40:664] PCM Hammer 014 [06:...

I tried this out last week with PCM Hammer just for fun but was not able to read it. The 97/98 ecus are much different so I didn't really expect it to work. Oddly enough GM used these ECU's in 1999-2000 C6500 trucks with the 7.4 before switching to the 0411 in 2001 with the 8.1. We just did a 0411 s...

From the info I have this should do it. Write full after the change.
Lean cruise patch for 12579405:

Not 100% sure where this came from so it may or may not be accurate but possibly handy.

Is the XDF you have for those OS' locked? I can check the memory locations on those settings if you like.

I have flashed newer OS' to the 9354896 PCMs. See the post NSFW linked above for possible wiring differences. I have one right here on my bench running OS 12212156. It works in my swap without a problem wired like a 2001 0411. PCMHammer reads and writes it using that OS and the available XDF's. So y...
